Question

select the correct answer.
what is the strongest relationship you can infer between two variables from this statement?
the number of minutes you can talk on a cell phone decreases as the phones battery charge decreases.
a. causation
b. correlation
c. association
d. no relationship

Explanation:

Causation means one variable directly causes a change in another. Here, a decrease in battery charge directly causes a decrease in talk - time. Correlation (B) just shows a relationship (like they change together) but not necessarily a cause - effect. Association (C) is a very general term for a relationship. Since there is a clear cause - effect (battery charge affects talk - time), it's causation.

Answer:

A. causation
